Abstract
A method includes mixing a solvent with a dry cathode mixture to form a slurry. The dry cathode mixture includes a cathode active material, a conductive diluent, and a polymeric binder. The method further includes removing the solvent from the slurry to form a composition and calendering, in a first calendering step, the composition to form a sheet. The calendering the composition includes passing the composition between calender rollers.
